Texas Instruments’ SimpleLink CC2592 range extender delivers a low cost, high temperature, small form factor design for worldwide operation

The SimpleLink CC2592 range extender provides up to a 7x improvement in range when paired with TI's 2.4 GHz low power RF solutions for ZigBee, 802.15.4, 6LoWPAN and Bluetooth low energy networks. The first such pairing to be made available is the CC2592 with the SimpleLink ZigBee CC2538 wireless microcontroller (MCU). The combined solution has -101 dBm sensitivity and +20 dBm output power, which raises the link budget by 17 dB and equates to up to a 7x range improvement.

As a low cost, industrial temperature solution, the CC2592 offers extended range for a variety of applications including gateways, electric and gas meters, home and building automation, lighting, safety and security systems. Additionally, the SimpleLink CC2592 range extender is a highly integrated solution with small external BOM, which reduces cost, simplifies layout and allows for smaller end-equipment form factors.

The CC2592 range extender operates over -40 to +125C; uses fewer passive devices for a complete configuration; and occupies a 4 x 4 mm QFN package. It costs $1.55 (100). An evaluation kit, CC2538-CC2592EMK, costs $99, and the related reference design is available for download here.
